Managua-Augusto Cesar Sandino-Las Mercedes, NicaraguaLanding (descent or approach)

On June 29, 1983, a Casa 212 Aviocar (registration YN-BYZ) operated by Aeronica - Aerolineas Nicaraguenses was involved in an aviation accident near Managua-Augusto Cesar Sandino-Las Mercedes, Nicaragua during landing or approach. No fatalities were reported. Investigators recorded the probable cause as: The co-pilot's accidental activation of the thrust reversers during the final approach caused an unplanned loss of altitude and a hard landing. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A); 4 related events involving the same aircraft type or operator are linked below.

An aircraft experienced a hard landing at Augusto Cesar Sandino Airport after the co-pilot accidentally engaged the reverse thrust during its final approach.

What happened

During the final approach phase into Managua-Augusto Cesar Sandino Airport, an operational error occurred involving the aircraft's propulsion systems. While descending toward the runway, the co-pilot unintentionally activated the thrust reversers. This premature deployment of reverse thrust resulted in a sudden loss of altitude and momentum.

As a consequence of the unexpected deceleration, the aircraft type impacted the runway with significant force. The impact was severe enough to cause structural damage that rendered the plane beyond economical repair. Despite the intensity of the hard landing, there were no fatalities or injuries reported among those on board.

Findings

Investigations into the incident concluded that the primary factor leading to the loss of altitude and subsequent heavy impact was crew error, specifically the accidental engagement of the reversers during a critical phase of flight.

Probable cause

The co-pilot's accidental activation of the thrust reversers during the final approach caused an unplanned loss of altitude and a hard landing.
